2. Sample Size Used for the Test Set and Data Provenance

The document states, "Non-clinical test data are submitted to support this premarket notification and to establish the decision concerning adequate safety and performance of the predicate device." However, it does not specify any sample size for a test set, nor does it mention data provenance (e.g., country of origin, retrospective or prospective) for any specific performance study related to the eKuore Pro 4T's diagnostic capabilities.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

This information is not provided in the document. The submission focuses on demonstrating substantial equivalence through technical comparisons and compliance with standards rather than a clinical performance study with human experts establishing ground truth for a diagnostic task.

4. Adjudication Method for the Test Set

This information is not provided in the document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of Human Readers Improve with AI vs. Without AI Assistance

No MRMC study is mentioned. The eKuore Pro 4T is described as a device that "electronically filter and transfer sounds to compatible software" and "can be used to record heart sounds...for diagnostic decision support." It is not presented as an AI-powered diagnostic tool, but rather as an electronic stethoscope that facilitates data transfer. Therefore, a comparative effectiveness study showing human reader improvement with AI assistance is not applicable in this context and not described.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

No standalone algorithm performance study is described. The device itself is an electronic stethoscope that captures and transmits sounds. The "eKuore Pro 4T Engine Java" is a library for third-party applications to communicate with the device, not a standalone diagnostic algorithm.

7. The Type of Ground Truth Used

The document does not describe any specific performance study that would require a defined ground truth (e.g., expert consensus, pathology, outcomes data) for diagnostic accuracy. The testing mentioned (non-clinical data, compliance with standards) relates to safety, electrical performance, software development, usability, and risk management rather than diagnostic accuracy against a clinical ground truth.

8. The Sample Size for the Training Set

This information is not provided because there is no mention of a machine learning or AI algorithm being trained by the device itself or an associated diagnostic software.

9. How the Ground Truth for the Training Set Was Established

This information is not provided, as no training set for an AI algorithm is mentioned.
